DRIVING-RUE SIDE-IVIO'JLIUN PLATE.

To all whom it may concern:

Be it known that 1, CHARLES RKARKEL, a citizen of the United States, residing at (llinton, in the county of Clinton, State of Iowa, have invented anew and useful improvement in Driving-Box Side-Motion Plates, of whiehthe following is a specification.

' It has heretofore been the custom to apply Babbitt metal to the hub side of axle boxes to obviate friction and wear but when this metal becomes worn or broken, it produces an objectionable side motion and in order to overcome this, it is necessary to run the locomotive into a shop, dismantle the same or take out the wheels, remove the boxes and renew the Babbitt metal, which is an expensive operation, as it requires several days time and the consequent loss of use of the locomotive.

In a prior patent granted to me on August 2nd, 1910, No. 966,31l, 1 have disclosed a greatly improved construction of side mo; tion plates, wherein the hub box is planed down and provided with upper and lower dovetailed flanges and a novel construction of sectional side motion plate coiiperating therewith.

In my present invention, l have produced a still; further improvement wherein the construction is further simplified and 1 employ a preferably one-piece side plate'of novel construction and material, as vulcanized fiber or material possessing similar characteristics, whereby a more durable, eficient and easily applied device than heretofore has been produced, the novel features of which will be hereinafter set forth.

To the above ends my invention consists of a novel construction of driving box side motion plates :tor locomotives, engine trucks and trailer boxes or any axle box where there is wear between the hub of the wheel and the side of the box resulting in lost or side motion, whereby the wear on the hub side of the boxes isv overcome by providing means for readily and economically taking up the side motion due to wear.

For the purpose of illustrating my invention, 1 have shown in the accompanying drawing an embodiment which is at present preferred by me, since the same will give in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention con sists can he variously arranged and organ.-

Application filed. March 14,1918. Serial No. 322,377.

ized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a perspective view of a driving box having a side motion plate thereon embodying my invention.

Fig. 2 represents a perspective view of the same driving box with my device removed therefrom to show' the manner of securing my device in position.

Fig. 3 represents a front elevation of my novelside motion plate in detached position. Fig. 4 represents an end view of Fig. 3. Fig. 5 represents a perspective view of a clamp employed, in detached position.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings- 1 designates the driving box which in its general construction may be similar to that ordinarily employed in cooperation with the axles of locomotive wheels, trailers, engine trucks and the like, except as hereinafter noted, said box having its hub side 2 planed down to the desired extent, as will be understood from Fig. 2.. At the lower portion of the legs 3, I locate the beveled or dovetailed seats 4 formed between said hub side 2 and the outwardly inclined or diverging walls 5.

At the lowerv portions of-said legs and in lieu of the divided side motion plates of metal having a Babbitt metal lining of the character seen in my prior patent aforesaid, No. 966,344, ll employ my novel construction ofa preferably onepiece plate 6 made preferably of vulcanized fibe1,.as seen in Figs. 1, 3 and 4, whose construction will now be described. The side motion plate 6 of vulcanized fiber consists of the top or arch shaped portion 7 having the depending legs 8 whose lower terminals are beveled, as indicated at 9, to conform to the bevels of the seats or dovetail portions 1, seen in'Figs, 1.

the parts are assembled by the the clamp 11, on the bolt 12,

10, which are adapted to be enwhose, shank lies in the recess 13, see Fig. 2,

and whose headis located in the seat or hole 1%, there being a'lock nut 15 employed if desired, as will be understood from Fig. 1. preferably locate the bolts as described, so as to diverge upwardly but it is obvious that other equivalent fastening devices may be employed.

The upper outer corners of the'side motion plates 6 have holes 16 therein which enable me to readily remove the plate 6 when desired by inserting the end of a steel bar or rod therein. The curved or arched portion 18 of the plate 6 is preferably a little smaller than the usual brass bearing 19 of arcuate form, which is fitted Within the box 1 in any usual or conventional manner thus preventing the brass from working out of the box toward the hub of the wheel if the brass. gets loose in the box.

The manner of assembling my device will be readily apparent to those skilled in the art. When it is desired to place aside plate in position it is only necessary to place the plate 6 in the position seen in Fig. l with the lower beveled edges 9 seated in the beveled or dovetailed seats 4, whereupon the tightening of the nuts 15 on the bolts 12 against the clamps 11 will quickly effect the securing of the upper and lower portions of the plate 6 in position.

The preferred construction of the clamps 11 will be understood from Fig. 5 the same having the beveled port-ions 17 and the hole 18 therein through which the bolt 12 passes. When the parts are assembled it will be seen that the bevel 17 on the clamp 11 engages the bevel 10 of a plate and also the bevel on the box, the bevel on the clamp forcing the plate 6 down into the bottom beveled seats 4 and also pulling said plate in against the face 2 of the box. A lock nut may of course be employed in conjunction with the nut 15.

Upon loosening the nuts 15 a plate can be readily removed for the purposes 'of inspection, replacement or repair. While I preferably employ for the plates .6 the material known as vulcanized fiber, which is especially adapted for this purposeby reason of its durable and wearing properties, it will be understood that my invention comprehends the use of other similar or equivalent material possessing the same characteristics and as I am the first to employ the material and construction herein above described my claims are to be awarded the scope accorded to inventions of this character.

It will now be apparent that I have devised a novel and useful driving box side motion plate which embodies the features of advantage enumerated as desirable inthe statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any'of.its advantages.

Having thus described my invention, what I claim as new and desire to'secure by Letters Patent, is:

1-. The combination of an axle or-driving box having its hub side planed down and provided with lower dovetail seats at the lower edges of the legs thereof, a one-piece plate of vulcanized fiber secured to said hub side of said box and conforming to the contour thereof, said plate having its lower terminals beveled to fit into said seats and having also beveled spots on its upper edge, fastening bolts located between the upper portions of said plate and box, and clamps on said bolts bearing on said beveled spots and the top of said box for securing said plate in position.

2. As an improved article of manufacture, a one-piece side motion plate constructed of vulcanized fiber and havin depending legs whose terminals are bevele the top of said side plate having beveled spots on each side of the center line thereof, and a curved internal wall substantially conforming to the curvature of the brass bearing of an axle box.
